The objective lectures - to form a knowledge of the natural resources as a source of livelihood and environmental management as one of the conditions for sustainable development
key words - natural resources,Sustainable development, society, nature, the protection of the environment, environmental management, wasting nothing, minerals.
the main issues and a summary of the content of:
1.The natural resources and their classification
2. Environmental management, occupational diseases and wasting nothing
3. Biological resources and food security
4.Environmentally sound energy sources as well as components of sustainable development ecosystems and society
natural resources - this is the basis of life of any human society. These include the means of subsistence of the people,Which do not have established their labor. This is water, soil, plants, animals, micro-organisms, minerals, space resources (energy from the sun). Among mineral resources can be allocated to energy (coal,Oil, gas, combustible slates) and mineral resources used directly or recycled (enrichment various ores). There are various classifications natural resources. For example,The use of natural resources are divided into production, health, aesthetic, scientific, etc. ; and the accessories to any components of nature - on land, water, forest,Mineral resources, energy and much more.
the most common classification natural resources on their political response. According to this classification all the natural resources are divided into should focus more energetically and vast (Diagram 12).A finite resources in turn, are subdivided into возобновимые, and. The возобновимым resources include a live component biosphere, some mineral resources (for example, salt,Осаждающиеся in lakes and marine lagoons), as well as soil, soil fertility which is formed over a large period of time and is one of the most scarce resource.However, the rate of use renewable resources must match the pace of recovery, otherwise возобновимые resources may become невозобновимыми. The невозобновимым resources include subsoil wealth of land,That will not be restored or are in the process of being restored are considerably slower than is their use. It is mining resources, which have emerged in special physico-geographical conditions,And such minerals, such as coal, oil, natural gas, which represent a dead upon and have evolved for millions of years. The inexhaustible resources include space,Climate and water resources. Space resources - this solar radiation and energy marine tidal variations and, due to the Moon impact on our planet.The solar radiation on the surface of the earth depends on the state of the atmosphere and extent of its muddy conditions. Climatic resources - this is the atmospheric air, precipitation, wind.Water resources - is a water supply of land. On a global scale this resource researchers, but on a local scale it can be exhausted (for example, the Aral Sea) .
People from the very first days of its existence was to exploit nature. However, in the contemporary world consumer attitude to the environment has moved all reasonable limits. Since the bronze age,Man has systematically obtain minerals. 18 century mankind has used ≈ 30 chemical elements, in the beginning of the 20th century in industrial processing was involved more than 50 elements,And now - more than 100 items in the table Mendeleev. Requirements for mineral resources has been steadily growing, and the demand for them is due, first of all, demographic growth. Starting with approximately 50-s, 20 century,Developed countries spend mineral raw materials more than the entire world for all предвоенное time. For the past 30 years of minerals iron ore and crude oil production more, than in the entire history of mankind.
Kazakhstan is one of the leading places in the world for stocks of minerals. The stocks lead, zinc, chromite ores, silver, tungsten, bismuth, vanadium and others.Non-ferrous metals our republic took the first place among the former Soviet republics, as well as copper, any, breast, коксующемуся coal, oil is one of the first places in the world.Large-scale production rates and use of mineral resources contribute to pollution of the environment by such elements, such as zinc, copper, lead, nickel, arsenic, molybdenum, selenium, antimony, cadmium, mercury, tungsten.In the view of many experts, the total toxicity these elements exceeds accumulated toxicity radioactive and organic pollutants. These elements,Organism in the environment, and actuating the food chain in the human organism, pose a serious threat to human health, causing not only physiological changes,But they affect genetic material (mutagenic effect) .
in a multifaceted and often unreasonable human activity reduces the number of species of animals (now turtle, ecological,Усуриискии tiger, borrows and etc. ) and plants (father's tutelage, Shen, цитверная hell, etc. ). The biological resources of the Earth are of the utmost importance, as determine, first and foremost,Biological basis for human activity. Biological resources quantify возобновимы (through reproduction), but qualitatively virtually is unrecoverable, as loss of species or ecosystems безвозвратна.
The biological resources include and genetic resources
